NITED STATES PATENT OFFICE.

METHOD OF IMITATING OBJECTS OF MAJOLICA-WARE.

SPECIFICATION forming part of Letters Patent No. 323,

823, dated August 4, 1885.

Application filed February 5, 1885. (No model.)

To all whom it may concern:

Be it known that I, JOHANN GOTTFRIED' MiiLLER, a subject of the King of Prussia, residing at the village of Schoneberg, near Berlin, in the .Kingdom of Prussia, have invented a new and useful Method of Imitation of Objects of Majolica, of which the following is a specification.

My invention relates to a'process for the pro duction of imitation majolica-ware-such as flat tiles or plates and the surfaces of vessels. The process consists in enameling metal plates in one color, impressing raised border-lines thereon to represent figures, and laying on enamel within such border-lines. For this purpose I proceed as follows: I engrave or etch the border-lines in a steel or zinc plate. Then I mix fire-proof porcelain color with varnish until it attains the consistency of thick paste, which paste I rub into the engraved parts of the plate and clean the plate. I then lay on the plate a thin paper and go over it lightly with a roller; then remove the paper, which will by this means have had the drawing or design transferred to it. I then take enameled metal plates or other materials made of enameled sheet-iron and impress the border-lines on the paper formed of the aforesaid composition onto the enameled metal plates, &c. I then burn these latter at a slow fire, and thus obtain the border-lines on the simple enamel in the form of raised lines. Within these border-lines I introduce enamel in such manner that each of the fields or spaces formed by the border-lines may receive any suitable color, according to the picture or design required. Finally, I subject the plates so prepared to burning in a furnace.

I am aware that in the specification No. 310,112 a process is described, according to 40 which glazed or enameled plates are by means of engraved plates impressed with coloring material impermeatedwith collodium, and the designs thus obtained melted into the underlying enamel. In my process the border-lines do not liquefy with the enamel, so that the colored enamels cannot run into one another. In the specification No. 256,415 a process is also described for making impressions in tiles and running metal into the same, but with this process also, my process has nothing in common, but it consists in impressing raised fireproof border-lines on enameled plates and running colored enamel between and within such border-lines, so that the different colors can- 5 not run into one another.

. What I claim as my invention, and desire to secure by Letters Patent, is-

A process for the production of enameled metal surfaces resembling majolica, such pro- 60 cess consisting in the impression of designs with raised border-lines in fire-proof porcelain color on enameled metal plates or surfaces of vessels madeof enameled metal, and the introduction and burning therein within and 6 between such border-lines of enamel.

In testimony whereof I sign this specification in the presence of two subscribing witnesses.
